I am a PhD student in the Statistical Laboratory of the University of Cambridge. My research currently focusses on frequentist validity of Bayesian procedures. My supervisor is Richard Nickl.


2011-2015 BA with MMath, University of Cambridge. My Part III essay, supervised by Richard Nickl and Jakob Söhl was on Nonparametric Drift Estimation from Low-Frequency Data.

2015-present PhD student in statistical theory, University of Cambridge
